WILLIAM A. ALLEN, OF COLEAX, TEXAS.

STALK-KNOCKER.

SPECIFICATION forming part of Letters Patent No. 372,735, dated November8, 1887.

(No model.)

To all whom it may concern:

Be it known that 1, WILLIAM A. ALLEN, a citizen of the United States,residing at Colfax, in the county of Van Zandt, State of Texas, haveinvented certain new and useful Improvements in Stalk-Knockers, ofwhichthe followingis a specification, reference being had therein to theaccompanying drawings.

This invention has relation to stalk-knockers, and among the objects inview is to provide a stalk-knocking mechanism that is simple ofconstruction, effective in operation, cheap,and which is adapted to beapplied to the running gear of an ordinary farmwagon.

Other objects and advantages will be herein after described, and thenovel features of the invention will be particularly pointed out in theclaims.

Referring to the drawings, Figure 1 is a side elevation of therunning-gear of an ordinary farm-wagon with the body removed andprovided with a stalk-knocking mechanism c011- structedin accordancewith myinvention. Fig. 2 is a rear elevation of the same; and Fig. 3 isa modification in perspective, hereinafter referred to.

Like letters of reference indicate like parts in all the figures.

A A representthe front and rear wheels, respectively,ofa wagon, A theaxle, A the reach, and A the bolsters,all ofthe usual construction.

13 represents an oblong framework, consisting of side and end rails,BB,wliichai'ci1iortised and bolted at each corner, as at B. Thisframe-work B is mounted upon the bolsters A" of the wagon, the body ofthe same having been previously removed,and may be retained in positionon said bolsters by any suitable devices, such as pins, bolts, fee. Therear end of the frame-work at each side provided with longitudinal slots13, having opposite pin-holes or perforations, B and adjnstablein theslots,and retained in position by means of pins B,passed through saidholes, are depending hangers G, having at their lowerends bearings G,(inthis instance open at one sidefland provided at their upper ends with aseries of adjusting-holes or apertures, 0 adapted to receive the pin B,and thus be raised or lowered to any de sired height from the ground.

An inclined braccrod, D,.perforatcd as at D, is pivotally connected tothe lower portion of each of the hangers O, as at D said brace beingadjustable within the frame-work by means of a pin, D. By thisarrangement of the brace the hangers may be swung away from or nearer totherear wheels, A,the object and purpose of which will be apparent.

The wheels A may be provided with a grooved or plain pulley, E, securedthereto in any suitable manner; but in this instance,and in order toprovide an ordinary wagon-wheel with a drive-pulley, I prefer to formthe pulley-wheel in sections E in the form of an arc of a circle. Thesesections are preferably castiron, and are formed with theoppositely-disposed lugs or ears'E adapted to embrace two adjacentspokes of the whoel,and when thus in position to form a continuouspulley or drivewheel. The sections shown in Fig. 1 are introduced withtheir lugs between two adjacent spokes near the rim of the wheel, andare then, by pressure or taps upon theirtops, driven down and seatedfirmly between the spokes, wedging in between the same. Several of thesesections being placed in position, their ends may be secured by metallicstraps or clips E".

Journaled in the open bearings G of the hangers O is the knocker-shaftF, (in this instance formed with the bearings orjournals F,) havingradiating knockers F at each end, and a similar intermediate knocker.Small pulleys F are formed at each side of the shaft, and from these andover the drive pulleys or wheels E extend a rope belt, or it may be abelt of any desired character, G. By this arrangement it is apparentthat when the wagon is in motion,

motion will be given from thepulloy E through the belt G to the pulley Fand its shaft, rotating the knockers and thus clearing a field ofstubble and stalks.

In Fig. 3 of the drawings I have illustrated a form of pulley-sectionwhereby the same is adapted to fit any size wheel. In this instance thelugs for embracing the spokes are disposcd toward each other, and thesection is introduced near the hub and driven upwardly to ward the rimof the wheel. The sections are preferably made somewhat shorter than inthe construction previously described, so that gene ally there is aspace between the same. The sections in this instance are secured toeach other as in the other form-namely, by the metallic straps or clipsIn the modification the straps are made longer, and are provided with aseries of perforations in order that the sections may be as far apart asthe size of the wheel will require.

By the adjustable brace-rod D the hangers may be adjusted so as to keepthe belt taut upon the pulleys.

Having described my invention and its operation, what I claim is- 1. Thecombination,with the running-gear of a wagon, of a framework mountedthereon and provided with vertically-adjustable hangers at its rear endcarrying stalk-knockers and their shaft, a diagonal adjust-able braceconnecting the hanger and the frame-work, and a drivingpulley formed insections, having spoke-embracing lugs, and connected to the knockershaftby means of a belt, substantially as specified.

2. The frame B, slotted as at B, and having the hangers 0, adjustable insaid slots, and provided with bearings C, having the shaft F, carryingknockers F in combination with the pulley'E, formed in sections E,connected as at E and having lugs E for embracing the spokes, saidpulley and shaft being connected I by the rope or belt G,substantiallyas specified.
